Video IP Cores
FPGAs are omnipresent in embedded boards and are now emerging as an inherent part of embedded systems, including real-time systems. From the role of simple devices that can hold glue logic, FPGAs have rapidly grown to multimillion gate devices that can hold entire digital systems. This rapid stride in technology has reached a stage where it is hard to design a complete system from scratch. Industry has started designing SoCs from a large repertoire of Intellectual Property Components or IP Cores sold by many vendors.
NeST has developed its own portfolio of IP cores by leveraging its vast experience in embedded - FPGA domain to identify the IP cores those are significant to the industrial community and to come up with easy-to-use, high performance, small footprint IP cores, all indigenously developed, implemented & tested in own applications.
NeST repertoire includes high performance real-time video processing cores, implemented and tested in FPGAs, like Video Scaler, Video Sharpness Enhancer, Gamma Correction and Video quality enhancement IP cores. These IP cores are ideally suited for all high performance real time video & image processing applications implemented in FPGA where input/ output delays are critical. All the IP cores are optimized for Xilinx Virtex-5 FPGA devices, and supports resolutions from 320x240 (QVGA) to 1280x1024 pixels (SXGA).
The Video Scaler engine resizes video streams. It converts an input video of dimensions Xin pixels by Yin lines to an output video of dimensions Xout pixels by Yout lines.
